该文提出了在供水泵站净扬程变幅较大条件下多年平均装置效率的计算方法。以泵站调速装置为核心，年费用最小为目标函数，借助于计算机，给出了供水泵站优化设计的计算成果。
This paper presents a calculation method of multi-year average unit efficiency under the condition of large head lift of water supply pump station. Taking the pump governor as the core and the minimum annual cost as the objective function, the calculation results of the optimal design of the water supply pump station are given by means of computer.
